British nationality in XXIst century British Colonial Empire

"The 1981 Nationality Act harmonised immigration and citizenship law
by incorporating patriality into the definition of citizenship. It created
British Dependent Territory Citizenship for those without direct blood links
to the UK. This status was especially anomalous for citizens in the oceanic
island dependencies. Invasion led to the restoration of citizenship to all
Falklanders, and the St. Helenians are promised restoration but the status
of the Ilois of the Chagos Archipelago remains unclear given that they were
forcibly removed to Mauritius by the British colonial administration. Muddle,
inconsistency and racism continue to mark the evolution of immigration and
citizenship law."
